  1. Question 1

    Q1. When 2-bromopropane is treated with a concentrated solution of alcoholic KOH at high temperature, the predominant reaction mechanism observed is:

    • A) SN1 mechanism
    • B) SN2 mechanism
    • C) E2 mechanism
    • D) E1 mechanism

    Answer: E2 mechanism

    Explanation: Secondary alkyl halides typically follow a mix, but high-temperature alcoholic KOH favors E2; SN2 is favored by lower temperatures and different bases.
